Sound Quality Evaluation of Nonlinear Distortion with Multitone

Xie Zhi-wen

Abstract

The present objective measuring methods for nonlinear distortion and the reasons why they cannot suffi-ciently reflect the characteristics of electro-acoustical system′s nonlinearity are analysed. The latest scientific researches of nonlinear distortion about subjective and objective sound quality evaluation around the world are introduced. It is pointed out that multitone will be a good choice to evaluate nonlinear distortion.
